Description Corallites are rounded to very elongated, with diameters of 10 to 15 mm. Walls may be fairly broad, giving rise to intercorallite distances of 3 to 6 mm. Septa are even, fine and closely spaced, which distinguishes this from Favia pallida with which it has often been confused, and both septa and costae have regular and fine teeth. The species is not as common as Favia pallida, but it occupies a very similar range of habitats. However, it is not as common in stressed habitats such as reef flats (Sheppard, 1998).
Colonies are massive. Corallites are crowded together, subcircular, with calices up to 12 mm in diameter. Septa are fine, numerous and regular. Paliform lobes are poorly developed. Colour: pale grey, green or brown, usually with calices of contrasting colour. Abundance: uncommon (Veron, 1986). [details]
